1 Claim.

This invention relates to a rod employed in hair waving. More specifically it has reference to a rod about which the hair may be wound and then temporarily held during the chemical or other treatment required to set the hair for producing a so-called permanent wave. Moreover the invention relates to rods of the type in which the hair is simply wrapped upon itself, the rod serving as a mandrel, to produce a simple coil, which when unwound will yield the desired wave, as well as those upon which the hair is wound in a helical spiral for providing the so-called Croquignole wave.

In one aspect the invention comprehends improvements in the subject matter of my United States Patent No. 2,010,112, granted August 6, 1935.

Rods having means for clamping the beginning strands of hair prior to wrapping of the hair are known. These may include pivoted, springbiased clamping fingers of various forms or may employ a rubber band or the like. In any case such constructions have proved clumsy to manipulate and bulky in use, or have utilized rubber or other materials which were affected by the heat or chemicals employ-ed in the process.

My invention has for its principal object the provision of a hair waving or curling rod which is adapted to clamp the terminal ends of the hair wound thereon without the use of separately attached movable means.

Another object is to provide a rod having a clamping feature as aforesaid which lends itself to incorporation in a simple, inexpensive plastic molding.

Still another object is to provide a rod according to the foregoing which is no larger in transverse dimensions than the body of prior known rods which are encumbered by mechanical clamping adjuncts.

Generally regarded the invention contemplates the provision of a one-piece substantially cylindrical rod which is axially split for a sufiicient portion of its length to accommodate therein the initial or starting strands of the hair, a portion of the remainder of the length of the rod being sunicientlty flexible to act as a hinge. To achieve the last mentioned result the rod is preferably comprised of a plastic material having some degree of resiliency. While not essential, the rod may be extended beyond the hinge and projections so formed as to provide a pair of fingers whereby the halves of the rod defining the slit may be manually separated to receive the strands of hair.

In the drawing which shows certain preferred forms in which the invention may be embodied in practice:

Fig. 1 is a plan view of a principal form of the invention;

Fig. 2 is a side elevational view thereof;

Fig. 3 shows a cross section taken on the line 3-3 of Fig. 2

Fig. 4 is a view similar to that of Fig. 3 but showing a modified cross section;

Fig. 5 shows a plan view of a modified form of rod adapted for use in a *Croquignole wave;

Fig. 6 shows a side elevational view of the rod of Fig. 5; and

Fig. 7 is a cross-sectional view taken on the line |--1 of Fig. 6.

Turning first to Figs. 1 to 3, there is shown a one-piece rod, in accordance with the invention, comprising an elongated body portion [0 of substantially circular transverse cross section and having a longitudinal contour which may be best described as concave. It has'been found that such cont-our lends itself best to wrapping of the hair on the rod, since, when a predetermined amount of hair is thus wound the center of the mass tends to accumulate to a greater thickness than the marginal portions. However, insofar as the invention is concerned, it will be understood that the external configuration of that portion of the rodupon which thehair is wound is not to be regarded as limitative. Such shape may be a conventional taper, of uniform diameter, or otherwise.

For the major portion of its length the rod is slit along a diameter thereof, as indicated at l2, to define a space within which the ends of the hair may be received and clamped. For clarity of illustration such slit has been intention-ally exaggerated in width. In order to reduce fatigue strains which may lead to failure by fracture the inner end [3 of the slit I2 is preferably cylindrically enlarged as shown at l3.

Between the aperture [3 and the right hand end of the body there is provided a neck portion [5 formed with a substantially circular cross section which serves as a hinge or pivot about which the two halves Iii-l6 defining the slit 12 may be swung as a result of the flexure of the material forming the neck portion. To achieve this end the rod l2, as heretofore pointed out, is preferably made of plastic composition of a resilient character, but one which is not capable of being deleteriously affected by the chemicals used in the waving process.

The two parts Iii-46 may be separated tem- 3 p orarily for insertion of hair into the slit [2 merely by wedging them apart with the fingers. However I may provide integral lugs 21-21 for facilitating such operation, and which may serve a dual purpose as will be described. Alternatively I may provide a pair of integral fingers 22-22, which, when pressed together, will act to pivot the parts l6|6 about the hinge portion l5. To assist in such function the fingers 2222 are preferably provided with a tapered inner surface so that, when brought together, there will be no interference therebetween.

If desired both lugs 2I-2l and fingers 2222 may be incorporated in the rod, not only for alternative convenience but for attachment of. a

rubber band 24 for securing the hair wound thereon until completion of thehair settingop-eration.

It is sometimes pref-erred to provide all or a portion of the length of; the body It with longitudinally extending ribs to serve as a friction surface, thus to facilitate winding of the hair and to maintain the wound condition thereof as wellas to crinkle the hair during treatment, thereby imparting an improved character'to the wave. Accordingly I'have shown :a plurality of ribs 25 spaced apart peripherally of-the body (Fig. 3). Preferably the disposition thereof is such that a rib borders each: corner of the slot 12 in order to reinforce the structure in those regions where fiexure maybe likely to cause fracture. While theribs 2 5; are shown asbeing shorter in extent than the body of the rod: they may obviously be coextensive with the. longitudinal extent of the concave surface of thebody, and may be straight (as shown) or conformed to the concavity.

In Fig. 4 is illustrated an alternative transverse crosslsection providing somewhat the sameresult as that of Fig. 3, and i'nwhich thej concavesurface is longitudinally grooved, as at 26, to define a plurality of longitudinal lobes.2'| whereby friction is increased and a crinkled formation imparted. to the hair.

Figs. 5tol 7 depict a further modification directed to use in the.Croquignole processl; In this case the body 3| comprises a helically formed lemen 1 193 5 7 r sverse cross section n oftaperedform. The slit-32, hinge portion 33; and g r 4- 4, ar ana gous l c io ll to h corresponding parts of that form of; the inven- 4 tion shown and described in connection with Figs. 1 and 2.

While I have shown particular embodiments of my invention, it will be understood, of course, that I do not wish to be limited thereto since many modifications may be made, and I therefore contemplate by the appended claim to cover any such modifications as fall within the true spirit and scope of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

A one-piece hair waving rod of resilient material comprising, an elongated body portion extending from one end of said rod throughout the major length thereof, said elongated body portion having substantially circular cross sections throughout its length and the ends thereof being of substantially equal diameters, said elongated body portion being further provided with a generally concavesurface extending intermediate the ends thereof, the central portion. of which surface is, pro'videdwith a p lurality of longitudinally extending ribs positioned in spacedrelation, a pair of fingers positioned in spaced relation located at the. other end of said, rod, a neck portion'p'ositioned' intermediate said body portion and said fingers which is, formed with a substantially circular cross section, said elongated. body portion being divided into two sections by a centrallyv positioned. longitudinal slot extending from said one end of said rodto said neck portion whereby pressure applied to. said fingers causing them to move toward each other Will result in flexure of said neck portion and separation' of said body portion sections.
